IMPROVEMENT IN PLATENS FOR OlL-PRES SES.

Specification forming a... of Letters Patent No. 200,250, dated February 12, 181 application filed January 25, 1878.

To all whom 'it may concern:

Be it known that I, STEPHEN BRITT, of the city of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Platens for Oil-Presses; and I hereby declare that the following is a clear, full, and exact description thereof, reference being had to the accompanying drawing, forming a part of this specification, in which- Figure l is a perspective view, and Fig. 2 a sectional view on the line am, Fig. 1, of a device embodying my invention.

The object of this invention is to overcome certain objections in the wood platens usually employed in oilpresses and the invention consists in the construction and adaptation of raised metallic clamps or cleats at the ends of the platen, whereby the device is strengthened andrendered more durable, and the separation of splinters from the wood which punctures and destroys the envelope containing the substance to'be compressed is avoided, and the oil directed to its proper channel without waste.

In the drawing, A represents the platen, which is usually composed of wood, and constructed of rectangular form, as shown. B B

are the clamps or cleats, (shown detached in Fig. 2,) which are made of metal and menforced by the projecting tenons b b, which serve to engagewith the guideways in the frame of the press, and maintain the platen in its proper position. These clamps or cleats are provided with double flanges c 0 upon the inner side and opposite to the projecting tenons b b,- and extend the entire length of the cleats,

as shown. Between these flanges the wood platen is secured by screws passing through the cleats and into the platen, or by any other suitable means.

It will be observed that the overlapping flanges c 0 project above the surface of the platen a distance equal to their thickness, and thereby serve to prevent the oil from running over the ends of the platen, and direct it to its proper channel. These clamps or cleats may STEPHEN BRITT.
